Work Done by a Gas | GCSE Physics Practice
When a gas is compressed or allowed to expand, work is done on or by the gas.
What happens to the temperature of a gas when you compress it quickly?
What is Work Done by a Gas | Practice?
"The energy transfer that occurs when a force is applied to a gas to change its volume."
What is the formula for density?
Why does a crisp packet puff up when taken on an airplane flight?
Calculate the pressure at a depth of 2m in water (density = 1000 kg/m³, g = 9.8 N/kg).
Specific heat capacity is the energy needed to raise 1kg of a substance by ____.
Gas Work
Work is done when a force moves through a distance.
Compressing a gas requires work to be done ON the gas.
This increases the internal energy of the gas.
An increase in internal energy leads to an increase in temperature.
Real World: A bicycle pump gets hot when you pump it quickly because you are doing work on the air, heating it up.
